Abstract
A resonance type non-contact power supply system is provided that includes power supplying equipment and an electric vehicle. The power supply equipment includes an alternating-current power source and a primary-side resonance coil for receiving power from the alternating-current power source. The electric vehicle includes power receiving equipment and a vehicle height control device mounted on the electric vehicle. The power receiving equipment includes a secondary-side resonance coil that receives power from the primary-side resonance coil, a rectifier that rectifies the power received by the secondary-side resonance coil, and an electrical storage device, to which the power rectified by the rectifier is supplied. A resonance system that includes the primary-side resonance coil and the secondary-side resonance coil is configured such that impedance thereof is adjusted by the use of the vehicle height control device when the electrical storage device is charged.
